I've checked interface and I couldn't find anything relating to tips or quoting anything the actual tips in game say...
I don't think they are changeable.. Maybe add them to Quest log if your not using Quests ?
Else you could use "-tips" then display a random tip to the user?
Interface would be the only place they would be, so they are hard coded into the the game and you need to use an alternate (such as above)
I think leave it for real old news that cannot be sorted the reason we had it in the first place was a server issue that we do not have anymore. I don't want to get rid of the archive just not put anything in it for now until we figure it out more
